True, but you have to start with something and that's an easy one.

If property owners are dumping best I could find in reference is Chapter 224 of the Waste Management Act:

(5) It shall be the responsibility of contractors to remove and dispose of
all construction waste material resulting from new construction or other works
on or at any premises.
(6) In the event a contractor fails to remove construction waste material
when required to do so by the Authority, the Authority may remove such
materials and recover the cost of such removal from the contractor.

So, with that in mind it should be a simple process (yeah, right) to have town council come in and by whatever means necessary remove said garbage and bill the property owner. Hit them hard in the pocketbook!
